Reasons for the shrinking area of Aral Sea

The reasons for the shrinking Aral Sea area are natural factors, man-made factors, ecological environment influence, social and economic influence, etc.

First, natural factors:

1. Climate change: Global climate change has caused the Aral Sea water source to decrease, the water surface evaporation to accelerate, and the water volume to decrease, thus making the Aral Sea area shrink continuously.

2. Drought: Due to the influence of global climate change and human activities, the rainfall in the Aral Sea basin is gradually decreasing, which leads to the decrease of water sources and the corresponding decrease of the amount of water injected into the Aral Sea by rivers, further aggravating the shrinking of the Aral Sea area.

Second, human factors:

1. Water conservancy projects: In the Aral Sea basin, many water conservancy projects such as reservoirs and dams have been built, which have changed the temporal and spatial distribution of water resources and greatly reduced the amount of water injected into the Aral Sea, resulting in a decrease in the Aral Sea area.

2. Agricultural activities: Aral Sea Basin is a developed agricultural area, which needs a lot of agricultural water, especially in dry years, which leads to a decrease in the amount of water injected into the Aral Sea and a decrease in the Aral Sea area.

3. Industrial development: With the development of industry, industrial water consumption has also increased greatly, especially in the process of developing oil, natural gas and other resources, a large amount of water resources are needed, which further reduces the amount of water injected into the Aral Sea, resulting in the shrinking of the Aral Sea area.

4. Water resources management: Poor management of water resources leads to waste and unreasonable utilization of water resources, reducing the amount of water injected into the Aral Sea, thus reducing the area of the Aral Sea.

Third, the ecological environment impact:

1. Water quality deterioration: As the amount of water injected into the Aral Sea decreases, the water quality of the Aral Sea deteriorates gradually, and the ecological environment of the Aral Sea deteriorates gradually, further aggravating the shrinking area of the Aral Sea.

2. Biodiversity reduction: With the shrinking of the Aral Sea area, the ecological environment of the Aral Sea has gradually deteriorated, which has gradually reduced the biodiversity of the Aral Sea and further aggravated the ecological crisis of the Aral Sea.

Four. Socio-economic impact:

1, fishery damage: Aral Sea is an important local fishery base. With the shrinking area of Aral Sea, fishery production is gradually affected, and the life of fishermen is also greatly affected.

2. Tourism is frustrated: Aral Sea is one of the famous local tourist attractions. With the shrinking area of Aral Sea, tourism has also been greatly affected. This has greatly affected the local economy.
